Arkham Intelligence data (unverified) indicates a custom entity controls 644 million SIREN — about 88% of the 728 million circulating supply (≈$1.8B at current prices). SIREN has risen ~340% in the past week (to $2.81 per CoinGecko) and nearly 1,300% in the past month. On-chain analysts warn the supply appears heavily concentrated in a small cluster of wallets, with roughly $950M in unrealized profit and most recent trading activity coming from existing holders rather than new users, prompting concerns the concentration could amplify volatility or enable manipulation.
